Abstract
A tire includes a ring shaped tire case formed from a resin material, a reinforcement cord having a higher rigidity that that of the resin material, wound in a spiral shape on the outer peripheral section of the tire case and having at least a portion of the reinforcement cord embedded in and making close contact with the outer peripheral section of the tire case when viewed in a cross-section along the axial direction of the tire case and a tread provided on the radial direction outside of a reinforcement cord layer formed by the reinforcement cord.
Claims4
A tire for rim mounting comprising a ring shaped tire frame body formed from a resin material having thermoplastic properties, the tire further comprising:
- a reinforcement cord member wound around an outer peripheral section of the tire frame body to form a reinforcement cord layer, when viewed in a cross-section along the axial direction of the tire frame body, having a portion of the reinforcement cord member embedded in the outer peripheral section of the tire frame body;
- and
- a tread provided at the radial direction outside of the reinforcement cord layer and formed from a rubber,
- wherein the reinforcement cord member comprises embedded portions and non-embedded portions,
- wherein the reinforcement cord member is in a state of close contact with the resin material throughout the embedded portions, and the non-embedded portions are bonded to the tread,
- wherein the reinforcement cord member is in tension, and
- wherein, viewed in a cross-section along the axial direction of the tire frame body, the reinforcement cord member is embedded in the outer peripheral section of the tire frame body by greater than ½ of the diameter of the reinforcement cord member.
